Pineapple Lilies not flowering
I had a couple of pineapple lilies in pots this summer and neither flowered - one I’ve had a couple of years with great success and the other was new. Both produced lovely foliage, but had no flowers. Question is, are they worth keeping for next year and if so, what should I do differently. (Both are in multipurpose compost in very sunny spots and were regularly fed with liquid feed).
